Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fabric edge sealing technology, and in particular relates to an edge sealing device for automotive seat fabric. Background Technology
[0002] Seat fabric edge sealing refers to the process of sealing the edges of seat fabric during seat manufacturing. The purpose of edge sealing is to enhance the aesthetics and durability of the seat, while preventing the fabric edges from wearing down, deforming, or being damaged by the external environment. During edge sealing, two pieces of fabric need to be superimposed and aligned. Since the fabric is mainly aligned manually, there is still a certain deviation at the edges after alignment. Therefore, the method of cutting along the edge is usually adopted to ensure that the fabric is fully aligned. However, during the cutting process, when the tool comes into contact with the fabric and when it separates, it will cause the fabric to be misaligned, affecting the alignment of the fabric. This paper proposes an edge sealing structure that can align the fabric. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides an edge-sealing device for automotive seat fabrics, which solves the aforementioned problems.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a sealing device for automotive seat fabric, comprising a cutter disc disposed within a frame, wherein multiple through holes on the cutter disc are perforated by pressure rods, and the inner diameter of the through holes on the cutter disc is larger than the outer diameter of the pressure rods; a pressure head is threaded to the bottom end of the pressure rod, and the diameter of the pressure head is larger than the diameter of the pressure rod; a circular plate is disposed below the cutter disc, and the diameter of the circular plate is larger than the diameter of the cutter disc; the circular plate is fixedly connected within the frame; the device further comprises a guide assembly for slidingly guiding the pressure rods; and a drive assembly for causing the cutter disc to slide at a uniform speed.
[0005] Beneficial effects
[0006] This utility model provides a sealing device for automotive seat fabric, which has the following advantages compared with the prior art:
[0007] The user places the first piece of fabric on the circular plate and rotates the connecting rod to position it above the fabric. At this point, the circular plate is pressed against the fabric. Therefore, when rotating the connecting rod, the user should press the fabric firmly to prevent it from shifting due to dragging. This process helps to smooth the fabric and prevent wrinkles. The user then places the second piece of fabric on top of the first, roughly aligning them, and rotates the connecting rod again to smooth both fabrics. The user can then start the motor. The lead screw fixed to its output shaft begins to rotate at a constant speed, causing the threaded frame to move linearly along its connection to the machine frame. This frame pushes the cutter head below it to slide towards the fabric. During this process, because the pressure rod extends through the cutter head, the pressure head contacts the fabric before the cutter head. When the pressure head contacts the fabric, the pressure rod cannot slide further downwards, causing the pressure rod and the cutter head to slide relative to each other. At this point, the top of the pressure rod... The connecting plate of the fixed connection begins to move linearly along its connection with the limiting rod, thereby compressing the spring fixed to it and causing it to deform. This deformation allows the connecting plate to exert force, ensuring that the pressure rod is pressed tightly against the fabric and applies vertical downward pressure. This prevents the two fabrics from slipping and becoming misaligned when the cutter head contacts and detaches from the fabric. Simultaneously, because the pressure head applies a vertical force to the fabric, it effectively prevents the two fabrics from skewing or shifting during pressure application. Furthermore, the diameter of the pressure head is larger than the pressure rod, effectively increasing the pressure-bearing area of the fabric and preventing excessive pressure that could cause localized damage. During this process, the cutter head continues to slide downward until it contacts the fabric and completes the pressing and cutting through the blade ring at its edge. The user can then reverse the motor to gradually reset the cutter head and pressure rod. Once the pressure rod detaches, the user should drag it away from the circular plate while pressing down on both fabrics. Attached Figure Description

Detailed Implementation
[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0014] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0015] Please see Figures 1-4 This invention provides an embodiment of an automotive seat fabric edge sealing device, comprising a cutter disc 201 disposed within a frame 101, wherein a pressure rod 202 penetrates through a plurality of through holes on the cutter disc 201, and the inner diameter of the through holes on the cutter disc 201 is larger than the outer diameter of the pressure rod 202; a pressure head 203 is threadedly connected to the bottom end of the pressure rod 202, and the diameter of the pressure head 203 is larger than the diameter of the pressure rod 202; a circular plate 305 is disposed below the cutter disc 201, and the diameter of the circular plate 305 is larger than the diameter of the cutter disc 201; the circular plate 305 is fixedly connected within the frame 101.
[0016] It also includes a guide assembly for slidingly guiding the pressure rod 202; and a drive assembly for making the cutter head 201 slide at a constant speed.
[0017] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific pressure head 203 described in the above embodiments. For example, the bottom of the pressure head 203 is provided with a rubber pad at the point where it contacts the fabric. The purpose of this setting is to facilitate the provision of cushioning between the pressure head 203 and the fabric.
[0018] Specifically, the guide assembly includes a connecting plate 204 and a limiting rod 205. The top ends of the plurality of pressure rods 202 are fixedly connected to their corresponding connecting plates 204, and the connecting plates 204 are slidably connected to their corresponding limiting rods 205. The top end of the limiting rods 205 is fixedly connected to the frame 207. The frame 207 is disposed above the circular plate 305. The bottom of the limiting rods 205 is provided with a pad with a diameter larger than its diameter.
[0019] It also includes a pressure assembly for pressing the pressure head 203 tightly against the fabric; and a connection assembly for connecting and fixing the cutter head 201.
[0020] Specifically, the pressurizing component includes a spring 206, which is sleeved on the limiting rod 205, and the bottom end of the spring 206 is fixedly connected to the connecting plate 204, while the other end of the spring 206 is fixedly connected to the frame 207.
[0021] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific spring 206 described in the above embodiments. For example, the elasticity of the spring 206 should be able to apply sufficient pressure to the connecting plate 204, thereby giving the fabric a sufficient limiting effect.
[0022] Specifically, the connecting assembly includes a shaft 208 and a ring 209. The shaft 208 is fixedly connected to the shaft center of the cutter head 201, and the ring 209 is fixedly connected to the shaft center of the frame 207. The shaft 208 is inserted into the ring 209.
[0023] It also includes a positioning component for limiting the position of the ring 209.
[0024] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific shaft 208 and ring 209 described in the above embodiments. For example, the shaft 208 and ring 209 are made of high-hardness materials. The purpose of this arrangement is to facilitate the avoidance of breakage under stress.
[0025] Specifically, the positioning component includes bolts 301, a plurality of bolts 301 are arranged around the ring 209, and the bolts 301 are threadedly connected to the ring 209. The shaft 208 has a groove corresponding to the bolts 301, and the bolts 301 are inserted into the grooves. The pressure rod 202 is fixedly connected to a guide plate 302, which is located above the cutter head 201. When the cutter head 201 is in contact with the guide plate 302, the bolts 301 are directly opposite the grooves on the shaft 208.
[0026] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific bolt 301 described in the above embodiments. For example, the position of the bolt 301 on the ring 209 corresponds to the position of the pressure rod 202 on the cutter head 201. The purpose of this arrangement is to facilitate the rapid insertion of the bolt 301 into the corresponding groove on the shaft 208 after the pressure rod 202 is inserted into the cutter head 201.
[0027] Specifically, the drive assembly includes a lead screw 303 and a motor 304. The frame 207 is threadedly connected to the lead screw 303 and slidably connected to the frame 101. One end of the lead screw 303 is rotatably connected to the frame 101, and the other end of the lead screw 303 is fixedly connected to the output shaft of the motor 304. The motor 304 is fixedly connected to the frame 101.
[0028] For the above examples, those skilled in the art should know that when implementing the above technical solutions, it is not limited to the specific motor 304 described in the above embodiments. For example, the motor 304 should be a motor with a self-locking effect. The purpose of this setting is to prevent the output shaft from reversing if an external force is applied to it after it has stopped and entered the self-locking state.
[0029] Specifically, the circular plate 305 has a shaft 307 on its side wall, and the shaft 307 is fixedly connected to the frame 101. A connecting rod 306 is rotatably connected to the shaft 307, and the circular plate 305 has a cutting groove adapted to the cutting ring at the edge of the 201 frame.
[0030] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific circular plate 305 described in the above embodiments. For example, the circular plate 305 is detachably fixed to the frame 101 by bolts. The purpose of this arrangement is to facilitate the simultaneous replacement of the corresponding circular plate 305 when replacing the cutter head 201.
[0031] In this embodiment of the invention, the user places the first piece of fabric on the circular plate 305 and rotates the connecting rod 306 to position it above the fabric. At this time, the circular plate 305 is in contact with the fabric. Therefore, when rotating the connecting rod 306, the user should press the fabric firmly to prevent the connecting rod 306 from dragging the fabric and causing displacement. During this process, the fabric can be smoothed to avoid wrinkles. Then, the user initially aligns the second piece of fabric with the first piece of fabric and rotates the connecting rod 306 again to smooth the two pieces of fabric. At this time, the user can start the motor 304. The lead screw 303 fixedly connected to its output shaft begins to rotate at a constant speed, causing the threaded frame 207 on it to rotate. The frame 207 begins linear motion along its connection with the frame 101, pushing the cutter disc 201 below it to slide towards the fabric. During this process, because the pressure rod 202 extends through the cutter disc 201, the pressure head 203 contacts the fabric before the cutter disc 201. When the pressure head 203 contacts the fabric, the pressure rod 202 cannot slide further downwards, causing it to slide relative to the cutter disc 201. At this point, the connecting plate 204, fixedly connected to the top of the pressure rod 202, begins linear motion along its connection with the limit rod 205, compressing the spring 206 fixedly connected to it. The deformation allows force to be applied to the connecting plate 204, ensuring that the pressure rod 202 is pressed tightly against the fabric, applying vertical downward pressure. This prevents the two fabrics from slipping and becoming misaligned when the cutter head 201 contacts and detaches from the fabric. Simultaneously, because the pressure head 203 applies a vertical force to the fabric, it effectively prevents the two fabrics from skewing or shifting during pressure application. Furthermore, the diameter of the pressure head 203 is larger than that of the pressure rod 202, effectively increasing the pressure-bearing area of the fabric and preventing excessive pressure that could cause localized fabric damage. During this process, the cutter head 201 continues to slide downwards until it contacts the fabric and passes through the cutter ring at its edge. After pressing and cutting, the user can then reverse the motor 304 to gradually reset the cutter head 201 and pressure rod 202. Once the pressure rod 202 disengages, the user should pull it away from the circular plate 305 while pressing down on the two fabrics. When it is necessary to adjust the shape of the fabric to be processed, the user should rotate the pressure head 203 to disengage it from the pressure rod 202 and loosen multiple bolts 301 in sequence, so that the bolts 301 stop limiting the shaft 208. Then, the user can pull the shaft 208 out of the ring 209, thereby removing the cutter head 201 from the pressure rod 202 as a whole, so as to replace the corresponding cutter head 201 to adapt it to the fabric to be processed.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
[0033] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.
[0034] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.
[0035] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.
[0036] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinge referred to in this application means that the component can rotate along an axial constraint.
[0037] In some cases, the sliding connection and hinge referred to in this application may also be damped, enabling the component to maintain in the desired position.
